Definitions

  • This invention relates to a dye scavenging substrate, and to a method for its manufacture.
  • the Specification discloses a method for the production of a dye scavenging substrate or cloth and to a method for its use.
  • the present invention is directed to a different aspect of the problem, namely effectively eliminating dyestuffs or colorants which have bled from or faded from the original material upon which they entered the bath or wash water environment. More specifically, the present invention is directed to a dye scavenging member or cloth; and the methods by which such a dye scavenging cloth or substrate is manufactured.
  • the invention therefore, provides a method for the production of a dye scavenging substrate which comprises the steps of:--
  • the compound which is a dye scavenging material, is glycidyltrimethylammonium chloride.
  • the alkaline solution is at a temperature of between 30° C. and 50° C. most preferably approximately 45° C.
  • the cellulosic material is a textile material which may take any form such as a woven, non-woven, or knitted fabric, a braided rope or bail or any other desirable configuration.
  • the cellulosic material may be paper or may be a naturally occurring material such as cotton or an artificially produced material.
  • a particularly preferred material is a blend of viscose and cotton.
  • the ratio of viscose to cotton is in the range 90:10 to 10:90.
  • the cellulosic material is a 50:50 blend of viscose and cotton.
  • step (c) is obtained by passing the substrate between a pair of hydraulically actuated rollers.
  • heating of the substrate in step (d) is achieved by passing the substrate through a series of rollers having a temperature of approximately 100° C. so that the substrate exiting the rollers is at a temperature of between 30° C. and 40° C., preferably about 35° C.
  • the temperature in step (e) is approximately 100° C. with a storage time of approximately 1 hour.
  • the pressure in step (g) is approximately 1.38 MPa (200 psi) and the material is passed through the rollers at between 92 mms -1 and 75 mm.s -1 , preferably approximately 83 mm.s -1 .
  • drying temperature in step (h) is between 95° C. and 115° C., most preferably about 105° C.
  • FIG. 1 is a schematic view of an apparatus for use in the method of production of the substrate according to the invention
  • FIG. 2 shows a comparison between the dye concentration remaining in an untreated bath, (plot A) compared with the dye remaining using a substrate prepared in accordance with the Claiborne Patent Specification (Plot B) and compared with a substrate prepared in accordance with the present Specification Plot C; and
  • FIG. 3 shows a comparison between the hours required to prepare an 800 m roll of substrate in accordance with a known teaching (Plot E) compared with the present Specification (Plot D).
  • an apparatus 10 for use in the production of the substrate which comprises a bath 11 containing a roller 12; a pair of hydraulically operated rollers 13,14; an infra-red drying unit 15; and a series of rollers 16.
  • a roll of substrate 20 is loaded onto a roller bar (not shown) for a first pass through the apparatus 10 and the material is fed into the bath 11 so as to pass beneath the roller 12, out of the bath 11 to between the rollers 13,14 and through the series of rollers 16 along a convoluted pathway to finally emerge therefrom and be taken up by a take-up roller (not shown) so as to provide a treated substrate roll 21.
  • the rollers 13, 14 are set to provide a pressure of about 1.03 MPa (150 psi).
  • the bath 11 is charged with a caustic solution via a line 32 and charged with dye scavenging material via line 33.
  • the infra-red drying unit 15 is not used.
  • the series of rollers 16 are heated to a temperature of approximately 100° C.
  • the treated substrate roll 21 is removed and wrapped in a water impermeable material and stored.
  • the storage time depends on the storage temperature which will be discussed in more detail later in the Specification.
  • the treated substrate roll 21 is again loaded onto the roller bar for a second pass and the material is fed into the bath 11 so as to pass beneath the roller 12; out of the bath 11 to between the rollers 13,14 and under the now in-use infra-red drying unit 15 and through the series of rollers 16 along a convoluted pathway to finally emerge and be taken up by the take-up roller.
  • the thus produced substrate is now stored and cut into appropriate size pieces.
  • the apparatus 10 may comprise two in number so as to provide a system in which the first pass and the second pass may be carried in a continuous (rather than by a batch) process with suitably arranged equipment disposed between each apparatus for enabling the material to be stored for the required time.
  • the dye scavenging material comprises a compound from the group consisting of:
  • N-trisubstituted ammonium 2-hydroxy-3-halopropyl compound having the general formula: ##STR3## or a salt of epoxy propyl ammonium having the general formula: ##STR4## wherein X is a halogen radical, Y is a chloride, bromide, sulfate or sulfonate, and the R's are the same or different and are methyl, ethyl, butyl or benzyl groups or an hydroxyl substituted derivative thereof.
  • a most preferred compound is glycidlytmethylammonium chloride.
  • the substrate roll comprises a cellulosic material.
  • the cellulosic material is a textile material which may take any form such as a woven, non-woven, or knitted fabric, a braided rope or bail or any other desirable configuration.
  • the cellulosic material may be paper or may be a naturally occurring material such as cotton or an artificially produced material.
  • the cellulosic material may incorporate a binder such as polyvinylacetate.
  • the cellulosic material may be viscose, cellulose or a mixture of cellulose and viscose.
  • a particularly preferred material is a blend of viscose and cotton.
  • the ratio of viscose to cotton is in the range 90:10 to 10:90.
  • the cellulosic material is a 50:50 blend of viscose and cotton together with a binder such as polyvinylacetate.
  • the substrate material in the first pass through the apparatus 10 moves at a rate of between 184 mm.s -1 and 167 mm.s -1 , preferably 175 mm.s -1 .
  • the substrate material in the second pass through the apparatus 10 moves at the rate of between 92 mm.s -1 and 75 mm.s -1 , preferably 83 mm.s -1 .
  • the caustic solution for use in the preparation of the alkaline solution comprises water and NaOH (pearl) in a range of from 5% NaOH to 50% NaOH or 2-10% NaOH or 5-10% NaOH and preferably either approximately 5% NaOH or approximately 4.7% NaOH.
  • the caustic solution and the compound are present in a ratio of between 1:0.119 to 1:0.26, preferably approximately 1:0.23.
  • the temperature of the solution is preferably about 45° C.
  • the acid solution comprises HCl in the range 4.3M-5M, preferably either approximately 5M or approximately 4.7M.
